Frequently asked questions
How much smaller will my PDF get?
It depends on the file. PDFs with large embedded photos shrink the most — often 40–80%. PDFs that are mostly text see little change, since there’s not much to compress.
Will this reduce image quality?
Yes, at higher compression levels. We recompress embedded images at the quality level you choose — text and vector graphics are left untouched.
Does this work on scanned PDFs?
Yes — scanned PDFs are usually just a sequence of embedded page images, which is exactly what this tool recompresses.
